Description

Technical Field

[0001] The invention belongs to the technical field of printing, and in particular relates to a printing device. Background Art

[0002] Intermittent flexographic printing, also known as intermittent flexographic printing, is a specialized form of flexographic printing. Its core characteristic is that the substrate or plate cylinder adopts intermittent motion (i.e., periodic starts and stops) during the printing process, rather than continuous, uniform speed operation. It is primarily used to address the needs of high-precision overprinting, printing on discontinuous substrates, or for the coordinated operation of multiple processes. Existing intermittent flexographic printing systems utilize gear transmission, which is costly. Furthermore, the ink roller structure of existing intermittent flexographic printing systems cannot be quickly replaced, requiring frequent cleaning. Summary of the Invention
